This patch introduces a new function intel_vgpu_reset_gtt() to reset the all GTT related status, including GGTT, PPGTT, scratch page. This function can free all shadowed PPGTT, clear all GGTT entry, and clear scratch page to all zero. After this, we can ensure no gtt related information can be leakaged from one VM to anothor one when assign vgpu instance across different VMs (not simultaneously).

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
